Filtration testing for spinnable polymer purity
In the production of spinnable polymers, ensuring purity and accurately measuring foreign particle concentrations is critical. Contaminants can disrupt manufacturing processes and compromise product quality, necessitating reliable filtration testing solutions.
Measures and identifies polymer contaminants
The Filtratest by Brabender is a specialized instrument for checking the purity and determining the concentration of foreign particles in spinnable polymers such as PET and PA, as well as other thermoplastic melts. The melt flows through a fine-meshed filter disc, which captures foreign particles. As these particles accumulate, the pressure increases, recorded by transducers during the measurement. Subsequent analysis of the sieves provides valuable data on the type and quantity of polymer contamination. The Filtratest includes features like a quick-change sieve drawer system, integrated pre-heating of the sieve package, and continuous extrusion by bypass option of the melt flow. This makes it an efficient, user-friendly solution for monitoring and maintaining polymer purity, particularly in industries like the chemical, food, and energy sectors.
